HINGE FOR DOORS.

sPncIFIcATIoN forming part of Letters'ratent No. 684,126, dated october'e, 1901.

Application tiled October 1| 1900. Serial No. 31,677. (No model.)

To @ZZ whom it may concern:

Be it known that we, ABRAHAM L. STUMP and FRANCIS BUCKER, citizens of the United States, residing at Shelby, in the county of Richland and State of' Ohio, have invented certain new and useful Improvements in Hinges for Doors, of which the following is a specification, reference being had to the accompari ying drawings.

Io Our invention relates to double acting spring-hinges for doors, and particularly Einges which are adapted to be fitted in the oor.

The object of our invention is to provide ceri5 tain improvements in the devices by which the spring is placed under tension when the door is swung in either direction and also to provide improved means for adjusting the tension of the spring.

zo In the'accompanying drawings, Figure 1 is a view of the lower portion of a door and doorjamb, the hinge being partially in section. Fig. 2 is a plan view on line 2 2 of Fig. 1, some parts being in section. Fig. 3 is a view of the spring mechanism, the cover-plate being removed. Fig. 4 is a vertical section on line 4 4 of Fig. 3, and Fig. 5 is a plan View of the adjusting-plate by which the position of the door With reference to the spring-operating mechanisrn is adjusted.

Referring to the drawings, 6 indicates the door, of which the lower inner corner is shown in Fig. 1.

7 indicates the door-jainb, and 8 indicates 3 5 ornamental molding between the doorand the jamb at opposite sides of the hinge. The up- Y per portion of the door maybe hinged in any suitable way to the jamb. The lower end of the door rests upon a pivot 9, arranged in a 4o vertical position thereunder and supported on a base-plate 10, as shown in Fig. 1. Antifriction-balls 11 are provided under the pivot 9 to avoid friction,asuitable socket being provided in thebase-plate 10 for the lower end of 4,5 the pivot and the balls, as shown in Fig. l.

12 indicates a cover-plate, which fits upon the base-plate 10 and is provided with a bearing for the pivot 9, as shown. As shown in Figs. 1, 3, and 4, the base-plate 10 is provided 5o with a marginal ange 13, which carries outwardly-extending ears 14 at suitable points,`

and the cover-plate 12 is secured to the baseplate by screws l5 passing through said plate and into the' ears 14. By this construction a box is provided adapted to contain the operating parts of the hinge.

The upper end of the pivot 9 extends. through the cover-plate'12 into a socket 16 in the lower end of the door 6, as indicated by dotted lines in Fig. 1. A socket-plate 17 is 6o screwed in the lower corner of the door to give the necessary strength, said socket-plate having an upturned flange 18 at the inner edge of the door, as indicated by dotted linesin Fig. 1 and as illustrated in Figs. 2 and 4. Screws 19 65 20 serve to hold the socket-plate in position.

2lindicates an adj usting-plate,which is earried at the upper end ot' the pivot 9 and extends transversely of the door. Said adjusting-plate is engaged by horizontally-disposed' 7o screws 22 28, which extend through the iiange 1S and bear against the outer edge of the ad# justing-plate 21, as shown in Fior. 2. By adjusting said screws the position of the door with reference to its pivot may 'be adjusted, 75 and by the engagement of said screws with the adjusting-plate the pivot 9 is caused to swing with the door.

As shown in Figs. 1 and 5, the pivot 9 is provided below the cover-plate 12 with one 8o or more crank-arms 24, which are tixedly secured to the pivot and carry a cranklpin 25.

YSaid crank-arms extend in a plane substantially parallel with that of the door, as shown in Fig. 3, and as therdoor swings the crank- Y pin 25 is swung from side to side.

26 indicates a spring extending substantially at right angles to the plane of the door and arranged on the base-plate 10. Said spring is supported on pivoted arms 27 28, 9o which are pivotally supported on pivots 29 30, respectively, carried by a plate 31, which is secured to the cover-plate 12 on the under side thereof, as best shown in Fig. l. For securing the 'plate 3l to the cover-plate 12 95 screws 32 are provided, which pass through the cover-plate and into screw-holes 33, provided in said plate 31. A number of screwholes 33 are provided, so that the plate 31 may be adjusted longitudinally of the coverlos plate for adjusting the action of the spring, as will be hereinafter set forth. The inner ends of the arms 27 2S, between which the spring 2G is supported, as shown in Fig. 3, are provided with concave recesses adapted to receive buttons 34, projecting from plates 35 at the ends of the spring 2G to permit the arms 27 28 to be adjusted readily to dilerent angles with relation to the spring. The pivots 2S) 30 of the arms 27 2S are placed, preferably, about midway between the ends of said arms, and the outer ends thereof are bent in toward each other and extend parallel with each other, but slightly separated, as shown in Fig. 3. The space between said Outer ends of the arms 27 2S is just sufficient to receive the pivot 9 and crank-pin 25, as shown in Fig. 3, the arrangement being such that whenever the crank-pin 25 is swung by the swinging of the door it will bear against one or the other of the arms 27 2S, swinging such arm on its pivot, and consequently compressing the spring 2G. lVhichever way the door swings, therefore, the spring 26 will be compressed, and consequently will act to return the. door to its closed position when it is released. By the construction described each of the arms 27 2S acts as a lever of the first class to compress the spring 26, and consequently by varying the relative position of the crank-pin 25 and the pivots of said arms a greater or a less leverage on said spring may be secured, depending on whether the pivots are moved from or toward the crankpin 25. By adjusting the plate 3l longitudinally of the hinge, therefore, the leverage of the crank-pin 25 may be varied and the action of the spring 26 correspondingly increased or diminished, as the case maybe. In order to facilitate the adjustment of said plate, an enlarged openingis provided i-n the cover-plate l2 and is closed by a screw-cap 36, as shown in Figs. l and 2. Said opening is large enough to expose one or more of the screw-holes in the plate 3l, so that by removing said screw-cap a tool may be inserted in one of said screw-holes and the plate 3l adjusted, the screws 32 having been first removed. To support the plate 3l when the screws 32 are removed, lugs 37 are provided on its under side, as shown in Figs. l and 4. In order to adjust the position of the door with reference to the spring mechanism, it is swung far enough to expose the screws 22 23, and by adjusting said screws the position of the door with reference to the adjusting-plate 2l and the operating parts of the spring may be varied, as desired, or the door may be carried toward or from the jamb. i

. That which we claim as our invention, and desire to secure by Letters Patent, is

l. A spring-hinge comprising a pivot, a pair of swinging levers, a spring between said levers and means connected with said pivot and operating one ofsaid levers to put said springs under tension when the pivot turns, substantially as described.

2. A spring-hinge compr1sing a pivot, a crank carried thereby, a spring, and a pair of levers piveted between their ends, said crank extending between two adjacent ends of said levers, said spring being connected with the opposite ends of said levers, whereby when the pivot turns one of said levers will be rocked to put said spring under tension, substantially as described.

A spring-hinge comprising a pivot, a spring, a lever for putting said spring under tension, means connected with said pivot and operating said lever when the pivot turns,and means for adjusting the relative positions of said operating means and the fulcrum of the lever to vary the action of said spring on the pivot, substantially as described.

e. A spring-hinge comprising a pivot, a spring, a pivoted lever for putting said spring under tension, means connected with said pivot and operating said lever when the pivot turns to put said spring under tension, and means for shifting the pivot of said lever to vary its action on the spring, substantially as described.

5. A spring-hinge comprising a pivot, a spring, a pair of swinging levers between which said spring is mounted, a crank carried by said pivot between said levers for swinging said levers when the pivot is turned, and means for adjusting said levers with reference to said crank to vary the action there- .of on the spring, substantially as described.
